Air filter / induction kit question

[Scott D]

I've put on a Pipercross Venom a few days ago and very very impressed with the kit, not had chance to log the peak g/s yet but throttle response feels much better compared to std airbox and less lag.

Had a good 2 hour drive today (an hour of that stuck in road works) and the filter housing was still cold afterwards, MPG has increased slightly and holding 17-18psi before was just about seeing 16psi with smoothed airbox, additional 3" air feed from lower bumper and a K&N panel filter.



Used to have a big Jetex cone on a while back with an air feed and while it sounded awesome there was defiantly a noticeable hesitation before the turbo kicked in. Did some logging and got same peak g/s figures of 186.96 with the Jetex and a CAI with Apexi filter on an hour before but felt better with the CAI on.

5th air filter setup this is now and providing peak figures are decent and can cope with the planned K04-001 will not be changing anytime soon.

Im running that pipercross air filter on the astra and it sounds great

Just ordered one plus put a best offer in on the housing

The shorter the induction tubing, the better / quicker the throttle response, but when I had my filter direct on the MAF it didnt seem as good at higher speeds (probably not getting the airflow needed)

Have since just run a mish mash of tubing to behind the passenger headlight and is good at low and high speeds

TBH, its only worth going for an enclosed kit, anything else is vulnrable to heat soak...

Always wanted the cone but never purchase as I keep hearing various reports....lag no lag...heat soak etc etc

i had a ram air cone filter cai kit and on the rollers it suffered very bad from heat soak hence why i removed it probably would of been ok if it had a heat shield of some sort and extra cold air feed to it

There's heatshield available on eBay.

The quality isn't brilliant, but they fit OK and do the job.

I feel my car pulls much better with my Jetex cone than it did with my smoothed airbox and pipercross filter. A fan on a dyno will not equal 70mph worth of air passing through the grill

I have managed to get some cold air ducting as well which will / should help.

you are correct but sold my cai bout a year ago  may get one that goes behind the bumper just so the pipe looks pretty in the bay
